Maybe this is obvious, but I needed some time to figure it out. In Affinity Photo for iOS, You can
- either save a native file to iCloud Drive (default)
- export a different file format to a storage provider of Your choosing
- OR use drag and drop to place a native file whereever You want.
Why is this important? It speeds up my workflow. I use AP on an iPad to sketch illustrations. I then take them further on the Windows desktop, which has pCloud as main cloud storage. Using the files app I can drop a copy of any sketch file into pCloud on the iPad, and once it has synced I can open it directly in Windows. This should work with Dropbox or any other storage provider that is available on both platforms.
